Remyelinated lesions in multiple sclerosis: magnetic resonance image appearance.
BACKGROUND Various types of pathologic mechanisms in multiple sclerosis (MS) can alter magnetic resonance imaging (MRI) signals, and the appearance of remyelinated lesions on MRI is largely unknown. OBJECTIVE To describe the MRI appearance of remyelinated lesions in MS. DESIGN Comparison of postmortem MRI findings with histopathologic findings. SETTING Brain donations from a general commu...
متن کاملIncreased mitochondrial content in remyelinated axons: implications for multiple sclerosis.
Mitochondrial content within axons increases following demyelination in the central nervous system, presumably as a response to the changes in energy needs of axons imposed by redistribution of sodium channels. Myelin sheaths can be restored in demyelinated axons and remyelination in some multiple sclerosis lesions is extensive, while in others it is incomplete or absent. The effects of remyeli...
متن کاملHypothalamic lesions in multiple sclerosis.
Demyelinating lesions of fiber bundles in and adjacent to the hypothalamus (i.e. the fornix. anterior commissure, internal capsule, and optic system) may be the basis for autonomic and endocrine alterations in multiple sclerosis (MS) patients. Therefore we investigated the presence and immunological activity of lesions in hypothalamic fiber bundles of 17 MS patients and 14 controls. In the MS g...
متن کاملCortical lesions in multiple sclerosis.
Although previous studies have shown that the lesions of multiple sclerosis may involve the cerebral cortex, there is little published research on the prevalence and distribution of such lesions. Using neuropathological techniques and MRI, a series of studies has been undertaken in order to assess this, in particular to identify their relationship to cortical veins. A serial MRI study showed th...
متن کاملAcutely damaged axons are remyelinated in multiple sclerosis and experimental models of demyelination
Remyelination is in the center of new therapies for the treatment of multiple sclerosis to resolve and improve disease symptoms and protect axons from further damage. Although remyelination is considered beneficial in the long term, it is not known, whether this is also the case early in lesion formation. Additionally, the precise timing of acute axonal damage and remyelination has not been ass...
